OIL-CUP ATTACHMENT FOR JOURNAL-BOXES.

SPECIFICATION forming part of Letters Patent No. 459,129, dated September 8, 1891.

Application filed April l1, 1891. Serial No. 388,514- (No model.)

To @ZZ whom t may concern:

Be it known that l, GEORGE B. \VOOD MANCY, a citizen of the United States, residing at Randolph, in the county of Cattaraugus and State of New York, have invented a new and useful Oil-Cup Attachment for Journal-Boxes, of which the following is a specification.

This invention relates to railway-cars, and more especially to the journal-boxes of the axles thereof, and to machinery and line-shafting, and especially to the journal-boxes thereof; and the object of the same is to provide improved means for lubricating said journals only when the car and machinery arein motion.

To this end the invention consists of the details of construction hereinafter more fully described and claimed, and as illustrated on the sheet of drawings, wherein- Figure l is a side elevation of the truck of a freight-car with my improved device mounted thereon. Fig. 2 is an enlarged transverse section through the oilcup.

Referring to the said drawings, the letters W designate the wheels, and F the frame, of the truck-in the present instance of a freightcar-and B are the bearings in which the ends of the axles turn.

Heretofore considerable difficulty has been experienced in freight-cars, line-shafting, and machinery, owing to the frequently-occurring hot boxes, which resulted from the journals running dry for want of oil. The object of this invention is to provide a device which will overcome this difficulty by avoiding its occurrence, and this I accomplish in the following manner and by the following-described devices.

R is a reservoir, which is preferably seated within a suitable casing O, and the latter has depending edges E so spaced that when the reservoir is set upon one of the straps of the frame F these edges will pass over the sides of said strap, and setscrews S may pass through the edges and abut against the strap to hold the casing in place. The latter is preferably of sufficient length to t closely between the vertical bolts V through the frame ateach side of the bearing B, as well shown in Fig. l. 3y this means the casing is held upon the frame and the reservoir is carried by the casing.

P is a pipe leading from the reservoir near its bottom outwardly, and this pipe may be provided with a section of a rubber or ilexia ble hose Il, if desired. The tip of the pipe is reduced and is bent in such shape that it may be introduced under the lid of the bearing B, so that the pipe shall deliver oil from the reservoirdirectlyonto the rotating axle. A cock K is located in the pipe near the reservoir, so that when desired the iiow of oil can be cut oit, and whereby it can at all times be regu lated.

Upon the reservoir R is located a chamber M, having a small airinlet I, as shown, and depending from this chamber to a point near the bottom of the reservoir is an air-inlet pipe A. Within the chamber M is a spherical ball L,Which,when the car is at rest, normally sets over and closes the upper end ot the pipe A but as soon as the car commences to move and the reservoir is thereby shaken up the ball L will. be jiggled from its seat, as will be clear.

Having constructed my improved lubricator as an article of manufacture, it can be mounted upon the frame F of any of the ordinary freight-cars now in use, or by a slight modification of structure upon that of the passenger-car, and upon the journal-box of shafting and machinery; but it is more especially adapted for freight-cars, and when in place the set-screws S prevent its dislocation. The tip of the pipe P is then inserted in the box B in an obvious manner and the cock K opened partially or wholly; but as there is no air-inlet the oil will not iiow. However, as soon as the car begins to move the ball L will move off its seat in the upper end of the pipe A, and air is thereby admitted to take the place of what oil may iiow down the pipe P. This flow of oil will continue as long as the car is in motion, but will cease when it again comes to rest.

Various changes in the details of construction may be made without departing' from the spirit of my invention.

That is claimed as new is l. In an oil-cup, the combination, with a reservoir, a casing surrounding the same and having depending edges adapted to tit over the strap of a railway car truck, and setscrews through one of said edges, of a pipe leading Afrom said tank and having areduced IOO tip, the Whole adapted for use as and for the purpose set forth.

2. In an oi1oup, the combination, with a reservoir adapted to be mounted upon the truck of a railway-oar, journehbox of machinery or shafting, a pipe leading therefrom to the bearing, and a oook in said pipe, of a chamber upon said reservoir having an air-inlet opening, an air-inlet pipe leading from the bottom of said chamber into the reservoir, and a bail Within said chamber normlly resting upon and closing the upper end of said pipe, as and for the purpose hereinbefore set forth.

In testimony that I claim the foregoing as i 5 my own I have hereto affixed my signature in presence of two Witnesses.
